The Motor & Motion Association is the manufacturing trade association for the electric motor and motion control industries. It promotes the electric motor industry through education, pre-competitive research and facilitation of technology transfer within the industry and in cooperation with ...
(Induction motors) Pull-up torque is obtained by starting the motor from rest at a pre-set torque value and specified motor terminal voltage. The maximum torque setting which the motor will accelerate to a speed higher than the speed at which breakdown torque occurs is the pull-up torque.
Industry:Electrical equipment
The rotating element of the magnetic structure which is found in non-commutator machines.
Industry:Electrical equipment
The angular displacement of the rotor or armature slots from one end to the other. It can be expressed in terms of the angular displacement from parallel. It can be expressed in degrees, bars or slots.
Industry:Electrical equipment
The difference in speed between the rotating field of an induction motor and the actual rotor speed. Slip is usually expressed as a percentage of the synchronous speed.
Industry:Electrical equipment
Actual motor speed in rpm with no external load and specified terminal voltage.
Industry:Electrical equipment
The actual motor speed in RPM with a specified external load and specified terminal voltage and frequency.
Industry:Electrical equipment
The slope of the speed-torque curve in rpm/oz.in. or rpm/Nm. Rm = R/KeKt.
Industry:Electrical equipment
This is the current at stall (locked rotor) with rated voltage applied. Is = Volts/Rt.
Industry:Electrical equipment
This is the actual torque at the output shaft under stall (locked rotor) conditions. Ts = (KtIs)-Tf.
Industry:Electrical equipment
The minimum current necessary to overcome static friction torque and start motor rotation.
